Description
Technical field
The present invention relates to body of a motor car auxiliary equipment, and in particular to a kind of motor vehicle seat back vibration of absorbing frequency-adjustable
Attenuator.
Background technology
Automotive seat can often produce strong vibration in the process of moving, and automotive seat dynamic comfortableness refers to that seat is expert at
The comfort experienced after chair framework and seat cushion transfer vibrations to human body under state is sailed, is mainly had with vibration characteristics
Close.The most sensitive frequency range of human body is：Vertical vibration is 4 ~ 8Hz, and horizontal direction vibration is below 2Hz, how to the greatest extent may be used
The reduction of energy ground is main target in the vibration of this frequency range.In order that automotive seat has good dynamic comfortableness,
Both at home and abroad generally using passive vibration isolation mode come the nuisance vibration of seat of decaying, as passive control effectiveness in vibration suppression is typically paid no attention to
Think, driver is vulnerable to all types of vibratory impulses, substantially reduce the comfortableness taken, therefore people devise various vibration dampings at present
Device improves riding comfort come seat vibration of decaying.
As disclosed in CN 1765654A " rubber spring vibration-dampening chair ", which is arranged on damping element under seat plate, profit
Change the rigidity of rubber spring with the change of different passenger sizes, so as to realize vibration damping, but the invention can only be for vertical
It is the vibration damping of cushion on direction, and to the vibration of backrest almost no attenuation.
And for example disclosed in 103332128 A of CN " vibration-damping seat for automobile ", the seat includes base support body, is arranged at base
The bearer connection part of backrest support body and the sheet taken for user on support body, the bottom of bearer connection part is connected to base
On support body, wherein, the vibration-damping seat for automobile also includes a shock absorber and a sliding bar, and sliding bar is arranged in can slide up and down
On backrest support body, and sliding bar lateral arrangement on backrest support body, the top of bearer connection part is connected on sliding bar, shock absorber
On base support body or backrest support body and there is the output end of an elastic telescopic, output end is connected with sliding bar.Though the invention
So can carry out vibration damping decay to backrest, but which is still changing damper bullet using the change of different passenger sizes
The rigidity of spring, so as to realize vibration damping.However, actually get on the car under different operating modes, the dynamic excitation frequency that seat is subject to
Change constantly, and frequency range be wider, just with driver's body weight change bring change absorber spring it is firm
The vibration that the mode of degree effectively can not decay under most driving frequencies, therefore, exploitation is a kind of to be applied to various vehicles and suction
The adjustable motor vehicle seat back vibration suppressor of vibration frequency just seems extremely necessary.
The content of the invention
It is an object of the invention to provide a kind of motor vehicle seat back vibration suppressor of absorbing frequency-adjustable, which can have
Effect decay vibration of the automotive seat under dynamic excitation, can adapt to the different driving cycles of automobile, and decay different frequency scope
Vibration, improve seat dynamic comfortableness.
The motor vehicle seat back vibration suppressor of absorbing frequency-adjustable of the present invention, including the base plate of lateral arrangement,
The left end of base plate is provided with left installing plate straight up, is provided with right installing plate straight up in the right-hand member of base plate, on the left side
Relative chute is respectively equipped with the inside of installing plate, right installing plate, it is characterised in that：One mass is transversely arranged on the base plate
Top, the two ends of the mass are respectively protruding in left installing plate, the chute of right installing plate；The base plate and mass it
Between can slide up and down along chute at least provided with a compression spring, the mass and drive the compression spring to do flexible
Motion.
There is support the upper end of the left installing plate, lower end with bolt connection, and is fixed on backrest bone by support
There is support in the left side of frame, the upper end of the right installing plate, lower end with bolt connection, and is fixed on backrest bone by support
The right side of frame.
The present invention has advantages below：After the vibration suppressor is installed on seat back-rest framework, in vibration suppressor
Mass can slide up and down in the chute of left and right installation board, and drive compression spring to do stretching motion, by dynamic excitation
The mechanical energy of generation is converted to the elastic potential energy of compression spring, therefore, it is possible to effective attenuation automotive seat shaking under dynamic excitation
It is dynamic.Under the different driving cycles of automobile, the height that mass is slided up and down is different, and the flexible amplitude of compression spring can not yet
Together, compression spring is stretched causes the change of its rigidity, and then have adjusted the absorbing frequency of vibration suppressor, so the vibration decays
Device can be decayed the vibration of different frequency scope, improve the dynamic comfortableness of seat.In addition, the motor vehicle seat back vibration decay
The structure and assembly technology of device is simple, with low cost, is suitable for heavy industrialization application.

Fig. 2 is the schematic diagram of left installing plate；
Fig. 3 is the A-A profiles in Fig. 2；
Fig. 4 is installed to the schematic diagram on seat back-rest framework for vibration suppressor.
In figure：1- seat back-rest frameworks, 2- compression springs, 3- base plates, 4- masses, the left installing plates of 5-, the right installing plates of 6-,
7- chutes, 8- supports.
Specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Fig. 1 ~ Fig. 4, the motor vehicle seat back vibration suppressor of the absorbing frequency-adjustable, including lateral arrangement
Base plate 3, is provided with left installing plate 5 straight up in the left end of base plate, is provided with right installing plate straight up in the right-hand member of base plate
6, relative chute 7 is respectively equipped with the inside of the left installing plate, right installing plate, a mass 4 is transversely arranged on the bottom
The top of plate 3, the two ends of the mass 4 are respectively protruding in the chute 7 of left installing plate, right installing plate；In the base plate 3 and matter
Two compression springs 2 are provided between gauge block 4, the mass 4 can be slided up and down along chute and drive the compression spring 2
Do stretching motion.
There is support 8 upper end of the left installing plate 5, lower end with bolt connection, and is fixed on backrest by support
There is support 8 in the left side of skeleton 1, the upper end of the right installing plate 6, lower end with bolt connection, and is fixed on seat by support
The right side of backrest frames 1.
After the vibration suppressor is installed on seat back-rest framework, the mass in vibration suppressor can be in left and right peace
Slide up and down in the chute of dress plate, and drive compression spring to do stretching motion, the mechanical energy that dynamic excitation is produced is converted to into pressure
The elastic potential energy of contracting spring, therefore, it is possible to vibration of the effective attenuation automotive seat under dynamic excitation.In the difference traveling of automobile
Under operating mode, the height that mass is slided up and down is different, and the flexible amplitude of compression spring also can be different, and compression spring is flexible to cause which
The change of rigidity, and then the absorbing frequency of whole vibration insulating system is have adjusted, the different frequency so vibration suppressor can be decayed
The vibration of scope, improves the dynamic comfortableness of seat.
